Got my 302 finally running!! after many set backs ,I have a set of ford motor sport finned valve covers , both sides are open and I can install vent style twist caps on them. Do I need to install a pvc vent to the air cleaner? Running a elect fan but motor seams a little hot to me. Need to figure out a few things yet ran it around the block a few times and it quit?? but started up after it sat a while any ideas what to check? It's a 1978 302 with a c4 transmission elderbrock carb. new style dist with built coil.
